SD-LTU Series
SD-LTU Series
The SDTORK SD-LTU Series Linear Transmission Unit is a high-performance linear drive solution designed for precise thrust control in multi-turn valve automation systems.
Engineered to be combined with SD-3001 / SD-3000 / SD-3002 Series Electric Actuators, the LTU converts rotary actuator motion into controlled linear thrust output for rising stem and linear valve applications.
Designed for heavy industrial environments, the LTU Series ensures:
High thrust capacity
Smooth linear movement
Precise positioning
Long service life
Reliable operation under continuous duty
The system is widely used in globe valves, dosing pumps, sluice gates, and other linear motion control equipment.
